I think I need some of this for Maddie's right ear - the ointment from the vets just isn't working. I looked at Walgreen's online for the ingredients and found 'Boric Acid Roach Powder' - that's not what I use is it?
You need 16 oz bottle of alcohol or witch hazel, 4 tablespoons of boric acid powder, and 16 drops of 1% gentian violet solution. Or @ least that what the formula on the woodhaven labs site recommends. If you check it out... it also gives you directions for the number of times per day etc.
